I cant believe this 2001 KX100 has a 420 chain on it. Even a TTR125 has a 428 and mine has a 428H on it. Has anyone changed over to a 428 or a 520, if so head me in the right direction with part numbers if possible.

I do know that a lot have people have gone to the 428 chain. I plan to do the same to my wifes bike. The funny thing is that the original owner of the kx100 that i bought for her had switched it over to a 428 chain. The kid that bought it from him had it changed back to a 420! :confused: (we are the third owners)

Probably some one at the kawi shop told him that he had the wrong equipment on the bike. :think:

Anyway - back to the 428 we will go.

Sprocket Specialist, Swinder, and/or Rebel Gears can set you up with the 428 chain & sprockets for it.

Can't believe it comes with a 420 chain. Was under the impression that all 85 cames stock with 428's.

Renthal has a kit to convert it over to a 428, part # k019

We just changed out the stock chain and gears on my son's '02 KX85 to 428 gears and a 428 O-ring chain. He races D-17 Hare Scrambles. Talk about lower maintenance! I'd highly recommend same for a KX100.

We tried the o-ring 428 - too much drag on the small engine. A good 428 racing chain lasts pretty good.

Renthal makes a good conversion kit.

This is an excellent mod but you'll need to file out the chain guide a bit so the wider chain doesn't rub.
